Collaborators’ joint authorship does not guarantee doctrinal identity

Evidence

When one or other makes an affirmation on their reciprocal agreement, this affirmation is valid only for the subject in question. Even the fact that one of them has written some chapters for a book written by the other is not an absolute reason why the book should be considered the result of a perfect agreement. There is no need to underrate the contribution of the second [Engels] but there is no need either to identify the second with the first [Engels with Marx] nor should one think that everything attributed by [Engels] to [Marx] is absolutely authentic and free from infiltration. — Antonio Gramsci, Selections from the Prison Notebooks, 1373
